79' K5 blazer lift questions
 

I have a 1979 blazer 4x4 it currently has 33x12.50 tires with no lift I jest bought truck an intend on fixing it up and keeping it. the tires rub fenders when I turn. I like the look of a 4 inch suspension lift and 33x 12.50's. what would I need to do, modification wise, to install this type of lift??? I found kits with shocks around $600.00 I need advice and recommendation!! I want to lift it not jest cut fenders! I want to know if it is needed to extend driveshaft? (expensive?) and extend steering shaft? or what are necessary modifications to install about a 4 inch suspension lift in my truck?

(high school kids truck) so im on a budget and slowly fixin her up!! ha
(not daily driver its a project truck)
all recommendations and help appreciated

the kit should come with everything you need. dont need to mess with the steering shaft or driveshafts, ive put a bunch of 6 inch lifts on these kinda trucks and never had any issue with any.

these trucks are pretty simple. lifts springs up front, lifts springs for the back, or blocks and a lifted steering arm which can be a royal pain in the butt to change
